AMP-activated protein kinase (AMPK) is a highly conserved sensor of intracellular adenosine nucleotide levels that is activated when even modest decreases in ATP production result in relative increases in AMP or ADP. AMPK contains a catalytic subunit (a) and two regulatory subunits (β and γ). Under lowered intracellular ATP levels, AMP or ADP can directly bind to the γ regulatory subunits, leading to a conformational change that protects the activating phosphorylation of AMPK. Phosphorylation by AMPK inhibits acetyl-CoA carboxylase (ACC) and results in reduced levels of malonyl-CoA product. AMPK inhibits mTOR signaling pathway by activating Tsc2 and downstream of Tsc2 by inhibiting Raptor component of mTOR complex 1.
Fig.1 AMPK regulates several physiological processes through phosphorylation of transcription factors and coactivators[1].
Due to its roles in fuel regulation, the AMPK pathway is regarded as a potential therapeutic target for diseases, such as diabetes type II, obesity and metabolic syndrome. Here Creative Biolabs offers AMPK signal pathway phosphorylation screening service with antibody array, which consists of 174 high-specific antibodies and more than 70 phosphorylation sites involved in AMPK signal pathways can be tested.
